The founder effect is a phenomenon that separates a small group of people from the original population by migrating or moving to a new isolated area. An example of the founder effect may be the settlement of previously uninhabited places, such as oceanic islands. The intended population will differ from the parent population in the gene pool, which will be devoid of some alleles. The composition of the gene pool of the new field is represented by randomly selected alleles. An example of the founder effect can be found in the blood groups of Aborigines who settled in Australia. Blood groups B and AB are absent among these indigenous peoples, as it is assumed that the founders of this population group did not possess it.
The bottleneck effect is a phenomenon that results in a sudden and rapid decrease in population as a result of epidemics, disasters, or various natural disasters (floods, fires, droughts, hurricanes). A small group of survivors recreates a population that is not genetically identical to the population from which it originated. As in the case of the founder effect, its gene pool is represented by a selective set of primary population alleles. An example of the bottleneck effect is the population of African cheetahs that escaped death during intensive hunting in the 19th century. This group gave rise to a new population with an altered gene pool, with individuals who became less viable and fertile.
Anthropogenesis - hypotheses of human origin
Anthropogenesis (Greek Anthropos - man, genesis - origin) - explains the phylogeny (approach) of man by describing the evolutionary processes that led to the creation of modern homo sapiens.
Hominids = hominids (Hominidae) is a systematic unit in the rank of a family (family of primates), which was identified in order to emphasize the possibility of a hypothetical common ancestor for chimpanzees and modern humans.
The characteristics of hominids include:
• the ability to assume an upright pose on two legs;
• Great intelligence;
• the ability to use tools;
Hypotheses of human origin
• The model of regional continuity (multi-regional, polycentric hypothesis) - according to this hypothesis, all human populations of modern humans descended from Homo erectus. This theory suggests that Homo erectus emigrated from Africa about 1.5 million years ago, spreading throughout the Old World (the region of Europe and Asia). As a result of the parallel evolution of geographically separated populations, local populations of Homo sapiens were created. By maintaining a connection that allowed the flow of genes, they maintained genetic unity.
